What This Test Measures

The test looks for HIV antibodies, which your immune system produces in response to HIV infection. These antibodies can appear within weeks to months after exposure, though results may take longer in some cases. This rapid method uses a reagent that reacts with antibodies if they are present, producing a visual result on the test device.

How the Test Works

Your blood sample is collected via a quick fingerstick. The test uses a rapid plasma reagent that detects antibodies to HIV-1 and HIV-2. A positive result indicates potential exposure, but further confirmatory testing is needed for diagnosis.

When to Expect Results

Results are typically available within 15–30 minutes after testing. However, a positive result requires additional testing to confirm HIV infection.

What a Positive Result Means

A positive result suggests you may have been exposed to HIV, but it does not confirm infection. You should follow up with your healthcare provider for confirmatory testing, such as a Western blot or nucleic acid test.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Early detection of HIV is critical for managing the infection and preventing progression to AIDS. This screening test helps identify potential exposure, prompting further evaluation and treatment options. If you test positive, your healthcare team will guide you through next steps, including counseling, testing, and potential antiretroviral therapy.

Frequently asked questions

How soon after exposure could I get a positive result?
HIV antibodies may take weeks to months to develop after exposure. Some people may test negative during the 'window period' (early stages of infection), so repeat testing is recommended if you suspect exposure.
What if my test is positive?
A positive result means you may have HIV, but it’s not a final diagnosis. Your doctor will order confirmatory tests to confirm infection and provide guidance on next steps, including treatment and support.
Can I still have sex or share needles if my test is positive?
No. If you test positive for HIV, it’s important to discuss safe practices with your healthcare provider. They can help you understand your risk level and access support to prevent spreading the virus.
